Abstract: Cornual pregnancy is a rare type of ectopic pregnancy, it could be easily missed because of its special location. To continued pregnancy may cause various complications such as miscarriage, placenta implantation and uterine rupture, etc.Penetrating placenta implantation is a more uncommon complication in obstetrics. When cornual pregnancy is combined with placenta implantation, it is very likely to cause uterine rupture and massive bleeding that endangers the lives of the mother and the infant. Here we report a case of uterine rupture caused by a cornual pregnancy combined with placenta implantation in the Second Hospital of Jilin University, and reviewed relevant literature. We investigate the causes, diagnosis and treatment of the disease, and provide ideas for clinical diagnosis and treatment.

Key words: Pregnancy, ectopic, Uterine rupture, Case reports, Cornual pregnancy, Placenta implantation
